Australian geologists have discovered a huge deposit of manganese nodules on the ocean floor off the Western Australian coast. The deposit covers about 600,000 km2.
Similar finds in other parts of the world have been found to contain iron as well as manganese and also traces of copper, cobalt, nickel, gold, uranium, and platinum. Those deposits, however, are far from port and transport facilities and are sparsely scattered. The Australian find is heavily concentrated and close to Fremantle, the shipping port for the state capital, Perth.
